A feature of the "modern theory" is that electric polarization is not well-defined in a metallic ground state. A different approach invokes the general existence of a complete set of exponentially localized Wannier functions, with respect to which ge

Undetected photon imaging based on four-wave mixing is demonstrated in silicon core fibers. Both amplitude and phase images are presented for a low-power telecom pump, with the potential for imaging at longer wavelengths discussed.

We present analytic expressions for the electronic contributions to the linear conductivity $\sigma^{(1)}_{3d}(\omega)$ and the third order optical conductivity $\sigma^{(3)}_{3d}(\omega_1,\omega_2,\omega_3)$ of three dimensional massless Dirac fermi

We show that using the electric field as a quantization variable in nonlinear optics leads to incorrect expressions for the squeezing parameters in SPDC, the conversion rates in frequency conversion, and the wrong behavior of cross- and self-phase mo

Recent progress in the development of direct band gap GeSn is exploited to investigate the optical injection and coherent control of spin currents in this group IV semiconductor. The analysis of these properties could provide essential information fo

We investigate spontaneous parametric downconversion (SPDC) in a waveguide array supporting two strongly coupled topological guided modes. We show that it is possible to generate photon pairs that are hyper-entangled in energy and path. We study the

Light is a union of electric and magnetic fields, and nowhere is the complex relationship between these fields more evident than in the near fields of nanophotonic structures. There, complicated electric and magnetic fields varying over subwavelength

We experimentally demonstrate the feasibility of the use of integrated linearly uncoupled resonators, which are coupled solely through the nonlinear interaction, to selectively enhance or suppress nonlinear processes. This is exploited to selectively
